Season 1

Jim's first cruise at the helm of the Sun Princess is complicated when his ex-wife orders him to take custody of their troubled fifteen-year-old son, Danny.

A twice-divorced couple tries desperately to avoid one another while sharing the cruise with brainless new mates. Engaged virgin anthropologists hope to sleep with other people to gain experience before their marriage. They set their sights on John and Suzanne.
